Concerns on Armor

My first concerns have been to work on a setting where guns are very intrinsic into the base of the game, and pathfinder guns make armor obsolete to the point of uselessness which hurts several classes which rely on armor for protection. This made me think that perhaps to make those classes more viable I needed to rework the cover system and give them some advantages in gunfights, however the more I thought about it the less this seemed like a good idea and I decided to keep the base gun & cover rules and instead give classes that rely on armor other advantages. At this time however I shall work on the races and primary 11 classes.
